如何验证重述

Question

我的表单中显示了重述，但当有人点击提交时，我只看到一个空白的白色屏幕。现在，我已经把有问题的php注释掉了，网站正常工作——你可以在www.necowindtest.com的注释选项卡下看到它。这是点击提交按钮时运行的php例程：注释部分之后的一切都正常工作。

<?php
// define variables and set to empty
$moniker = $commentdate = $comment = "";
//          
//set timezone to mountian
date_default_timezone_set("America/Denver");
//
/*This starts the possibly problematic statements   
//
// files placed in root of server
require_once "recapthchalib.php";
//
//exit for troubleshooting move this up if you didn't get a message or down if you did
exit("MADE IT THIS FAR");
//              
//secret key
$secret = "6LfUTwoaAAAAAGIDFC8FqCoZX0TOTzSKFyOKT57h";
//          
//empty response
$response = null;
//          
//check secret key
$reCaptcha = new ReCaptcha($secret);
//
//if submitted check response
if ($_POST["g-recaptcha-response"]){
$response = $reCaptcha->verifyResponse(
$_SERVER["REMOTE_ADDR"],
$_POST["g-recaptcha-response"]
);
}
//
//display form or thank you for submission
if ($response != null && $response->success) {
echo "Hi " . $_POST["moniker"] . " thanks for the submission";
}
else {
echo "Sorry captcha verification was unsuccessful";
}
//
//This is the end of the problematic statements

谢谢Alvaro，花了一段时间，但我发现了如何让bluehost显示php错误。现在我越来越近了。
